Our main aim is to produce important new scientific data of the mechanisms of traumatic brain injury (TBI) and for the diagnostics of TBI, by using high-quality prospectively collected material. We aim at characterizing different injury types and combinations, improving their reliable detection, improving individual diagnostics and decision-making and at the same time clarifying the occurrence, detection and effect of different pathophysiological phenomena. In other words, we aim at raising the diagnostics of TBI to an improved level and clarifying the injury mechanisms in a way that facilitates the development of new treatment interventions. The main principles in our research activities are national and international networking, close collaboration between clinical and basic research, continuous connection between clinical care and scientific research, and creation of internationally unique facilities for clinical research of TBIs.
